[crazythinking]

问题描述

当将如下json转换为包含org.joda.time.DateTime的对象时，发生如题异常；

{"data":"tp20140101","effectiveDate":1388505600000}

该对象定义如下：

public class TimelineParameter implements HasEffectiveDate, ReverseIndexInter {

	public DateTime effectiveDate;
	
	public String data;
	
	public List<InnerParameter> paramList;
	
	public TimelineParameter(String data, DateTime effectiveDate)
	{
		this.effectiveDate = effectiveDate;
		this.data = data;
	}
	
	@Override
	public Date getEffectiveDate()
	{
		return effectiveDate.toDate();
	}

	@Override
	public void setEffectiveDate(Date effectiveDate)
	{
		this.effectiveDate = new DateTime(effectiveDate);
	}

	@Override
	public List<Field> fillIndexFields() {
		List<Field> fields = Lists.newArrayList();
		try {
			fields.add(TimelineParameter.class.getField("data"));
			fields.add(TimelineParameter.class.getField("effectiveDate"));
		} catch (NoSuchFieldException e) {
			// do nothing
		}
		return fields;
	}
}

环境信息

请填写以下信息：

• OS信息： windows
• JDK信息：Openjdk 17
• 版本信息：2.0.39

重现步骤

如上图，该方法断点处发生异常

换成1.2.83 可正常处理；

期待的正确结果

同1版本兼容，可正确转换
